Description
Book SynopsisDiseases and Conditions in Dentistry: An Evidence-Based Referenceis the ideal, one-stop guide for dentistry clinicians to keep at their side.
- Provides a quick reference for the busy clinician covering diseases and conditions in endodontics, periodontics, prosthodontics and restorative dentistry
- Offers identically formatted chapters following the same clear and concise layout with detailed clinical cases and evidence-based discussions
- Features a companion website with additional clinical photographs, radiographs, and case notes
Trade Review"In order to make each chapter easier to read, the author uses the same format, including definitions, etiology, classifications, epidemiology, relevant history and special investigations, diagnosis, prognosis, treatment challenges, management options, maintenance issues, and relevant evidence from the literature […] The book is an excellent guide for under- and post-graduate students, and for those preparing for the ORE,"MFDS, MSc, MRD, ISFE, MClinDent, and DClinDent specialty exams.
